There was a major bug in a previous HIPS 7 hotfix release to do with sound velocity, in that it didn't apply it properly. Caris have recently released a fix for this and it should be downloaded by anyone using HIPS 7 and applying Sound velocity corrections to their data. The Caris text is as follows;

*** Important Notice - Hotfix 3 now available ***

Hotfix 3 for HIPS/SIPS 7.0.1 is now available for download via the Online Customer Service webpage (http://support.caris.com). This hotfix addresses the previously reported SVC issue reported in the February 23rd notice. Once this hotfix has been installed, it may be required that users re-run any SVC that had been previously carried out in HIPS/SIPS 7.0.1 (Hotfixes 1-2) with the aforementioned inputs and options. We apologize greatly for any inconveniences or confusion that this may have caused.

Yesterday (1st March) NetSurvey successfully completed the Isle of Wight Survey. The data looks fantastic and Ben, Gaelle and the MMT team on Seabeam have done a fantastic job. Images will be posted shortly. In the meantime here is Ben and Jacob (Seabeam's skipper) hard a work.

This year to enhance the processing & reporting turnaround for the Maritime & Coastguard Agency contract that Marin Matteknik have held for the last 5 years and that NetSurvey have provided the QC and reporting for, one NetSurvey Cat A Surveyor will be onboard all the time. Some specific NetSurvey processing routines are being adopted by MMT to enhance the product, in particular the Applanix POS MMS methodology for vertical control.

JP Cheminade is on board at the moment and can be seen working hard with near faultless data by the looks of it!

NetSurvey are currently surveying to the South of the Isle of Wight for Natural England. The survey is to look at the Chalk Reef Habitats and we are using the MMT survey vessel Seabeam.

Ben Thompson and Gaelle Granjard are the two NetSurvey hydrographic surveyors. MV Seabeam is MMTs 24/7 small vessel (17m). Joel, Christian and Christoffer from MMT are also on board.

Here is the presentation that I gave at the Maritime & Coastguard Agency's CHAS 2010 seminar yesterday.

I found www.marinetraffic.com last week. This appears to be a worldwide AIS realtime site and was quite up to date, only about 2 minutes old. I checked this by looking at myself on the Red Funnel ferry to the Isle of Wight last week. The screen grab shows the Port of London vessel Yantlet heading home after surveying off Burnham-on-Crouch today.

For anyone out there who uses the free mbsystem multibeam processing software (developed by Dave Caress at the Monterey Bay Aquarium Research Institute (MBARI)) and has also got Fledermaus version 7 then in the upcoming 7.1 release you can now take the mbsystem fbt files and clean them or grid them in Fledermaus. This will allow you to use the CUBE algorithm to speed up your processing. Once you have finished your data cleaning/processing in Fledermaus you can unload the changes back to the fbt files and use these within mbsystem or GMT as you do currently. The files seems to load really quickly and that is both for creating DTMs and also for creating the PFM data structure which Fledermaus uses to process the data.

Here are some screen captures showing the lines and a grid in 2D in DMagic and then the PFM loaded into Fledermaus. Lastly a point cloud view coloured by line in the 3DEditor where you can reject bad points.
